R&D head help ,,,,

[dr_guido85]

hi,,,
Came across R&D cyl head today and have a few questions ,,,any help will be appreciated ,,been doing some research and cant seem to find any post on its setup and installation,,,
I have a 98 gtx limited,,,do i need to modify anything or is it just bolt on??
there are 2 extra openings in the head for cooling.,,do i have to modify the cooling system to connect them?or just leave them screw plugs in there??
How do i know which size domes it has??

I see no point in putting this head on a 99 Gtx with no other mods. Just my opinion

I tend to agree with Adam, however if anyone on this forum can help you it would probably be [MENTION=51824]Matt Braley[/MENTION]

Unless you want to shorten the life of the engine....

The R&D head will increase the compression and the stresses on the engine. So if it is already tired it could help it go Boom. The jetting would need to be changed, higher octane fuel would be needed and the o-rings do not seal on the 951 as good as the factory gasket.

I know a guy who just had to switch to ADA from R&D because he could not get replacement domes. If there is no markings then you have to fill the domes with liquid and measure it. You need at least 49cc for pump gas.

Don't spend time and money making your engine less reliable. Leave it alone.
